  1. PACS/MII in Digital Radiology Dr. Jun Ni, Ph.D., Associate Professor Department of Radiology Carver College of Medicine The University of Iowa PACS/MII in Digital Radiology (Lecture 001)

  2. (Lecture 1)Introduction Dr. Jun Ni, Ph.D., Associate Professor Department of Radiology Carver College of Medicine The University of Iowa PACS/MII in Digital Radiology (Lecture 001)

  3. Notification: The curriculum is developed based on the contents from the book “PACS, A Guide to Digital Radiology,” by Keith J. Dreyer, DO and Ph.D, David S. Hirschorn, MD, and James H. Thrall, MD, and Amit Mehta, MDPublished by Springer PACS/MII in Digital Radiology (Lecture 001)

  4. Historical Change • The message of the textbook delivers: • Picture Archiving and Communication Systems (PACS) was considered as a possible solution; but not reality • Now it becomes not just a reality but a necessity

  5. Historical Change • Why is that? • Most larger radiology departments have gone digital, and smaller departments and imaging centers are not far behind. • Printing CT and MRI exams for interpretation is like printing your e-mail in order to read it. • Ten years ago this analogy would be lost on most radiologists because they didn’t know what e-mail was, but now virtually all radiologists know what it is and use it on a regular basis.

  6. Historical Change • Why is that? • Digital cameras are ubiquitous, and millions of consumers, radiologists among them, are filling up hard drives instead of shoeboxes with their family photos. • By now most radiologists have viewed images on the Internet and have begun to recognize the benefits of managing images on a computer.

  7. Benefits • The benefits of PAC systems are clear. • Within seconds after an image is acquired, it can be viewed by the radiologist and any number of referring and treating physicians simultaneously. • There is no film to be lost or stolen. CT exams with a thousand images are becoming common and simply cannot be managed effectively on film. • PACS viewing software can be used to dissect, analyze, magnify, or reformat image data in an infinite number of ways. • Virtual private networks can transmit whole exams across the globe within seconds for remote consultation, perhaps in the middle of the night to a radiologist who is just starting her day. • Today’s archives can keep decades of studies online in a cost-effective manner and in a much more organized and accessible manner than ever possible in a traditional file room.
